Current and planned ports

Freq. Pol Mode NinoTNC mode Status Links
144.9375 MHz V NinoTNC QPSK 3k6 IL2P+CRC 0101 active GB7RDG GB7BSK GB7WOD MB7NPW
50.650 MHz V NinoTNC GFSK 4k8 IL2P+CRC 0100 planned GB7RDG MB7NPW GB7IOW?
70.4875 MHz V NinoTNC GFSK 4k8 IL2P+CRC 0100 considered GB7EBN?
432.650 MHz V NinoTNC GFSK 9k6 IL2P+CRC 0010 considered GB7IOW? G7BCS?

As far as possible we hope to use the forthcoming 6m port for linking and the 2m port for user access; with only the 2m port currently operational locked NETROM routes have been implemented to the following nodes with which we have a (mostly!) reliable circuit: GB7RDG (Reading, Berks), GB7BSK (Basingstoke, Hants), GB7WOD (Woodley, Berks) and MB7NPW (Pewsey, Wilts).
